YARN-TWISTING DEVICE.

-. application mea my a, 1927. serial No. 1ss,oe's.

This invention, generally stated, relates to reel or twisting machines for twisting two or more strands of .yarn and reeling the. same, and has more especial relation to 5 the provision of means whereby the cops may be readily removed from their carriers at will' also in the provision of a tension device for the twisted yarn; and in the provision of means whereby two or more I strands of yarn may be twisted and reeled simultaneously upon the same machine.

The principal object of the present invention maylbe said' to reside in the provision of means whereby the cops may .be moved from their respectivel spindles readily and in Y an ex editiousmanner.

A fixrther object of the present invention is to provide means whereby two or more strands of arn ma `be twisted for presentation to a vanker d taneously with said twisting operation upon the same machine.

A still further object ofthe present invention is to provide a tension device cooperative in' connection with said twisting device, whereby the twisted yarn is presented to a hanker device in proper form.

Other and further objects of the present invention reside in the provision of general details of construction and in the arrangement and combination of parts for attaining the results sought by the foregoingobjects.

The invention consists of the novel con' struction hereinafter described and finally claimed. A

The nature, characteristic features and sco of the invention will be more fully un erstood from the following description taken in connection withthe accompanying drawings forming' part hereof, and in which:

Fig. 8, is a view in section taken upon the line 8-8 of Fig. 7.

For the purpose of illustrating my inven tion AI have shown in the ,accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliablevresults, although it is to be understood that the various instrumentalities of which my invention consists ,can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as' herein shown and described.

Referring .to the drawings, the reference number 1 designates what is termed in the trade a spindle rail; 2 designates a cop-rail;

3 designates a shaft upon which is mounted cop shaft 7. The reference numeral 8 designates a so-called hankerupon which the twisted yarn is wound.V All of the above described parts arel of conventional type and form no part of the present invention, Each cop shaft 7, of which there may be any number, has fixed thereto a member 9 adapted for the support of co s 10, whereby the cops 10 in revolution o the shafts 7 are rotatedin a well understood manner. Between the cop-rail 2, which is ixed, and the pulley 6, which is fixed to shaft 7, is arranged a tension spring 11, see Fig. 2. In this connection it is to be noted that each cop shaft 7 has antifriction connection 'as at 12 and 13 with the supports 1 and 2; 'Located immediately shaft'7 is the device shown in Figs. 6, 7, and 8. This device, which is horizontall varranged in the form of a bar 14, is vertlcally movable with respect to the cop shaft 7 underl above the cops 10 upon each.,

arrow in Fig. 6 against the tension of spring 15, the notched part 17 of the bar 14 may be disengaged from the lug 18- of the collar 16, so that the bar 14 may be rotated around its vertical axis to become disaligned from the cops 10 which position it previously occupied. In this connection it is to be noted that there is in screw-threaded relation with each cop shaft 7, a bolt'19 having a head 20, and between the head 20 and the top of the bar 14 the spring 15 is positioned. Thus, by lifting the bar 14 against the spring 15 it is possible to move the bar 14 around its vertical axis. When the bar 14 is thus moved around its vertical axis so that the notch 17 no longer enga-ges the lug 18 the bar 14'restsv upon the top edge of the lug 18 so that the bar 14 may be positioned at an desired angle with respect to the cop sha t 7. Thus, a cop 10 may be readily removed from its spindle 21 .because of the fact that the bar -14 may be partially rotated around its vertical axis so as to be out of alignment with the cops 10. Each bar 14 is 'provided with an eye 22 for the passage therethrough of, arn` from a cop 10. Each eye 22has lea ing thereto a slotted part 23,' as clearly shown in Fig. 7.

The yarns passed from the cops 10 through the eyes 22 are caught in the funnel 24 which has xed relation with respect tothe top rail 25 of the twisting machinev said rail being supported by means of a standai 26 from the spindle rail 1. lThis/funnel(` 24 is slotted as at 27 see Fig. 4, so that in the revolution of the cops 10 and the bar 14 or thread guide, the yarn from the cops maybe readily in- -troduced into the funnel. The guide 24 is made of a funnel or cone shape, with the narrow'or pointed position thereof nearest the'tensioning device and' its wider portion near the cops, so as to converge the relatively I divergent threads passing upwardly through the eyes o guides22 and to direct the plu-J rality of th eads-being twisted to a common Vpoint or focus which materially aids in the twisting operation. Furthermore, the cone shaped, guide 24 while efectively guiding the yarn threads at the same time affords a liberty of movement and tends to prevent entanglement, as will be apparent. During the passage of the yarn from the cops 10 to the funnel 24 the yarn is twisted, as clearly shown in Figsl and 2, and from thence passes to a tension device, adescription of which will now be given, it being understood that the funnel 24` is part of the tension device. The reference numeral y28designates an angular bracket fixed as at 29 to the top rail 25. This angular bracket 28, which is clearly .shown in" Figs. 3 and 4, carries a pair of pivotal rollers 30 and 31, which are freely rotatable. Having pivotal connection with the bracket -28 is an arm 32 provided with a. finger piece 33. Pivotally adapted to impinge upon the peripheries of the rollers 30 and 31, this position being clearly shown in Fig. 3.- The roller 34 is maintained in abuttmg position with the rollers 30 and 31 by means of the spring 35, see Fig. 4, oneend of which is connected as at 36 to the bracket 28, and the opposite end of which is connected as at 37 to the arm 32. This provides a very simple, efficient, and comparatively inexpensive tension device, and the twisted yarn passing over the rollers 30 and 31 and under the tension roller 34 passes through eye 37 upon the cop-rail 2 to the hanker device 8, all of which is clearly shown in Fig. 2. In this connection it is to be noted that while a description has been given of but one set of cops and a single tension device, and although two sets are shown in Fig. 1 of. the drawings, it is to be understood that the number of cop shafts 7 toi gether with cops and tension devices may be increasedor diminished as practice may two cops andY put them on a twisting mai chine. and after the yarn has been twisted,

it was necessary machine. l i

By my invention, I take care of both the above stepsin one apparatus, whereby there is a saving of $.041/2 per ound in the twisted yarn, and I can in a dition get up to 40 turns of twist to ten inches.
